Abstract: Aiming at the far field property of high power pulsed semiconductor laser and the requirement of laser power density and spot uniformity by laser guidance, the coupling scheme of multi-aperture space is proposed and the advantages are analyzed theoretically. For nanometer multilayer chip high power semiconductor laser polarization, the polarization beam combining of two high power semiconductor array lasers is studied based on the principle of polarization multiplexing. Experimental results show that output power of the system is almost twice as high as that of a single laser, and the coupling of multi-aperture coupling and polarization coupling can meet the light spot requirements of remote control guidance.
